Smoked turkey replaces the more traditional choice of bacon in this rendition of braised collard greens. Nice and garlicky, the greens are spiced up with red chili flakes, with a bite of acidity from cider vinegar and lemon juice. And, since the turkey's pretty lean, we finish it off with some butter to give the pleasantly bitter, tender greens the rich, mouth-coating quality that pork belly typically provides.
